Question

Quizplus · Accepted Answer

A bimetallic strip consists of two different metals with different coefficients of thermal expansion which are bonded together. When it is heated or cooled, the strip bends due to the different rates of expansion of its two components. This principle is used in various applications, including thermometers, thermostats, and choke controls in old automobiles. Therefore, all of the options given in the question use a bimetallic strip.
